Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 43F5R0 are qualified based on matching the following critical parameters:

• Resistance value: 5 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Termination count: 2

All listed substitutes meet these electrical and mechanical specifications. Differences in packaging format (Bulk vs. Cut Tape), physical dimensions, compliance certifications, and moisture resistance features are secondary considerations that may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection among substitute parts should be based on the following criteria derived from provided specifications:

Ohmite 43F5R0E: Identical electrical specifications and physical dimensions to the main part. RoHS Compliant status makes this suitable for applications requiring regulatory compliance. Bulk packaging format. Highest inventory availability (6823 pcs).

Vishay Dale ALSR035R000FE12: Meets all electrical parameters. Includes moisture-resistant feature. ROHS3 Compliant. Smaller physical dimensions (4.57 x 12.70 mm). Suitable for space-constrained applications requiring enhanced environmental protection. Lower inventory (820 pcs).

Vishay Dale RS02B5R000FS70: Meets all electrical parameters. Includes moisture-resistant feature. RoHS non-compliant status. Cut Tape packaging format. Intermediate physical dimensions (4.75 x 14.22 mm). Moderate inventory availability (1999 pcs).

Frequently Asked Questions (FAQ)

Q: Can the Ohmite 43F5R0E directly replace the 43F5R0?

A: Yes. Both parts share identical electrical specifications (5 Ohms ±1%, 3W, ±50ppm/°C) and physical dimensions (5.60 x 15.10 mm). The primary difference is RoHS compliance status. The 43F5R0E is suitable for applications requiring RoHS Compliant components.

Q: What is the difference between the Ohmite and Vishay Dale options?

A: All parts meet the core electrical requirements. Vishay Dale parts (ALSR035R000FE12 and RS02B5R000FS70) include moisture-resistant features and offer different physical dimensions. Ohmite parts maintain the original form factor.

Q: Are the physical dimension differences significant?

A: Physical dimensions vary slightly across substitutes. The Ohmite 43F5R0 and 43F5R0E are 5.60 x 15.10 mm. The Vishay Dale ALSR035R000FE12 is 4.57 x 12.70 mm (smaller). The Vishay Dale RS02B5R000FS70 is 4.75 x 14.22 mm. Verify PCB layout compatibility before selection.

Q: Which substitute has the best availability?

A: The Ohmite 43F5R0E has the highest inventory at 6823 pcs. The RS02B5R000FS70 has 1999 pcs. The ALSR035R000FE12 has 820 pcs.

Q: What packaging formats are available?

A: The Ohmite 43F5R0E is supplied in Bulk packaging. The Vishay Dale RS02B5R000FS70 is supplied in Cut Tape (CT) format. The Vishay Dale ALSR035R000FE12 is supplied in Bulk packaging.
